WASHINGTON (CNN) --The Food and Drug Administration is planning to move beyond its recent actions on ephedra and step up its scrutiny of the health effects of various other herbal supplements, a top federal health official said Tuesday.

In a speech in Mississippi, FDA Commissioner Mark McClellan said new manufacturing and labeling regulations for dietary supplements will be released later this year.

"When these regulations are finalized later this year, the public will not be faced with 'buyer beware' any longer," McClellan said.
